The SR 40 Mini2 receiver provides three status LEDs each for channels 1 and 2, indicating ON/OFF status, received signal strength (RF OK), and audio clipping (AF CLIP). The VOLUME control sets the level at the ¼" output jack. Each receiver comes with a universal 12-V switched mode power supply with EU, UK, and US adapters. The illuminated ON/OFF button switches both channels on and off simultaneously.

The PT 40 Mini bodypack is probably the smallest and lightest transmitter in its class. A reliable mini XLR input allows you to connect every compatible AKG miniature microphone.
The rugged HT 40 Mini handheld transmitter features an ON/OFF/MUTE switch and a sturdy wire-mesh cap protecting the cardioid dynamic microphone element. Battery life is the same legendary 30 hours off a single AA battery as for the standard WMS 40 models, reducing the need to replace batteries and thus saving real money in the long run.
